Description

Technical Field

[0001] This utility model relates to the field of casing injection molding part unloading mechanism, specifically to a casing injection molding part unloading mechanism with an anti-blocking mechanism. Background Technology

[0002] The outer casing injection molding part unloading mechanism is an automated or semi-automated device on the injection molding production line used to remove the molded plastic outer casing parts from the mold and transfer them to subsequent processes (such as inspection, packaging, assembly, etc.). It is a key piece of equipment connecting the injection molding machine with subsequent production stages, directly affecting production efficiency, product yield, and equipment stability.

[0003] Traditional shell injection molding unloading mechanisms lack anti-blocking functions during the unloading process. As a result, when shell parts accumulate due to their complex shapes and uneven cooling, manual shutdown and cleaning are required, which not only delays work time but also affects production efficiency.

[0004] Therefore, it is necessary to invent a casing injection molding part feeding mechanism with an anti-blocking mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a shell injection molding part unloading mechanism with an anti-blocking mechanism. When the injection-molded shell plastic part is pushed from the mold into the unloading slide, a photoelectric sensor inside the unloading slide can detect any abnormalities in the shell plastic part inside the unloading slide. If the shell plastic part remains stationary for more than 3 seconds, the input end of the photoelectric sensor is fixedly connected to the output end of the electric push rod, allowing the electric push rod to push the internal piston rod and the front push rod to move in the limiting slide groove inside the unloading slide, thereby pushing away the blocked shell plastic part. At the same time, after being pushed to the bottom, the limiting slide groove is arc-shaped, allowing it to slide directly into the upper limiting slide groove. Then, the piston rod pulls the push rod to move back from the upper limiting slide groove. This avoids contact with other plastic shells when the parts retract. This solves the problem mentioned in the background art that the traditional shell injection molding part unloading mechanism lacks an anti-blocking function during the unloading process, resulting in the accumulation of shell parts due to their complex shape and uneven cooling. This requires manual shutdown for cleaning, which not only delays work time but also affects production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shell injection molding part unloading mechanism with an anti-blocking mechanism, including an unloading slide for unloading shell plastic parts; The telescopic rod is hinged to both sides below the front end of the feeding chute, and a support column is movably sleeved on the outside of the telescopic rod; A photoelectric sensor is fixedly installed on the inner wall of the feeding chute to monitor blockages. A limit groove is provided on the other side of the inner wall of the feeding chute. A hinge shaft is rotatably connected to the inner wall of the feeding chute. An electric push rod is fixedly connected to the outside of the hinge shaft. A piston rod is slidably connected inside the output end of the electric push rod. A connecting sleeve is fixedly connected to the front end of the piston rod. A push rod is movably sleeved inside the connecting sleeve. A support frame is installed on both sides below the front end of the unloading slide for support, and a damping shock absorber is fixedly connected to the top of the support frame.

[0007] Preferably, the surface of the telescopic rod is provided with threaded grooves, and the external thread of the support column is connected to a bolt, which passes through the telescopic rod and the support column.

[0008] Preferably, the limiting groove is elliptical, and the electric push rod is rotatably connected to the unloading slide.

[0009] Preferably, the other end of the push rod slides in a limiting groove, and the length of the push rod is less than the inner width of the feeding chute.

[0010] Preferably, the upper end of the damping shock absorber is hinged to both sides below the front end of the unloading slide, a servo motor is fixedly installed on the outer side of the support frame, and an abutment block is fixedly connected to the output end of the servo motor.

[0011] Preferably, the abutting block is oval-shaped, and the upper end of the abutting block abuts against the lower part of the feeding chute.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention, through the arrangement of a feeding slide, photoelectric sensor, limiting slide groove, hinge shaft, electric push rod, piston rod, connecting sleeve, and push rod, can prevent blockage in the feeding slide. When the injection-molded plastic shell is pushed from the mold into the feeding slide, the photoelectric sensor inside the feeding slide can detect any abnormalities in the plastic shell inside the feeding slide. If the plastic shell remains stationary for more than 3 seconds, the input end of the photoelectric sensor is fixedly connected to the output end of the electric push rod, allowing the electric push rod to push the internal piston rod and the front push rod to move in the limiting slide groove within the feeding slide, thereby pushing away the blocked plastic shell. At the same time, after being pushed to the bottom, the limiting slide groove is arc-shaped, allowing the part to slide directly into the upper part of the limiting slide groove. Then, the piston rod pulls the push rod back from the upper limiting slide groove, thus preventing it from contacting other plastic shells when it retracts. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The illustrated housing injection molding part unloading mechanism includes an unloading slide 1 for unloading housing plastic parts; Telescopic rod 2 is hinged to both sides below the front end of the feeding slide 1, and support column 3 is movably sleeved on the outside of telescopic rod 2; A photoelectric sensor 6 is fixedly installed on the inner wall of the feeding slide 1 to monitor blockage. A limit groove 7 is opened on the other side of the inner wall of the feeding slide 1. A hinge shaft 8 is rotatably connected to the inner wall of the feeding slide 1. An electric push rod 9 is fixedly connected to the outside of the hinge shaft 8. A piston rod 10 is slidably connected inside the output end of the electric push rod 9. A connecting sleeve 11 is fixedly connected to the front end of the piston rod 10. A push rod 12 is movably sleeved inside the connecting sleeve 11. Support frame 13 is set on both sides below the front end of the unloading slide 1 for support. Damping shock absorber 14 is fixedly connected to the top of support frame 13. When the injection-molded plastic shell is pushed from the mold into the unloading slide 1, the photoelectric sensor 6 inside the unloading slide 1 can detect the abnormality of the plastic shell inside the unloading slide 1. When the plastic shell is stationary for more than 3 seconds, the input end of the photoelectric sensor 6 is fixedly connected to the output end of the electric push rod 9, so that the electric push rod 9 pushes the internal piston rod 10 and the front push rod 12 to move in the limiting slide groove 7 inside the unloading slide 1, thereby pushing the blocked plastic shell. At the same time, after being pushed to the bottom, the limiting slide groove 7 is arc-shaped, and it slides directly into the upper part of the limiting slide groove 7. Then, the piston rod 10 pulls the push rod 12 to move back from the upper limiting slide groove 7, thus avoiding contact with other plastic shells when it retracts.

[0019] like Figure 1 and Figure 2 As shown, the surface of the telescopic rod 2 is provided with threaded grooves 4, and the external thread of the support column 3 is connected with bolts 5, which pass through the telescopic rod 2 and the support column 3. According to the height between the material feeding slide 1 and the mold, the telescopic rod 2 and the material feeding slide 1 are adjusted by extending and retracting from the support column 3. After the height is adjusted, the bolts 5 pass through the support column 3 and the telescopic rod 2 to fix them.

[0020] like Figure 3 As shown, the limiting slide 7 is elliptical. The electric push rod 9 is rotatably connected to the unloading slide 1. The electric push rod 9 pushes the internal piston rod 10, which in turn pushes the push rod 12 to move telescopically within the limiting slide 7. When the push rod 12 moves from the lower side of the limiting slide 7 to the bottom, the bottom is arc-shaped, which allows the push rod 12 to move from the lower side of the limiting slide 7 to the upper side. Since the electric push rod 9 is also rotatably connected to the inner wall of the unloading slide 1, as the push rod 12 moves inside the limiting slide 7, the electric push rod 9 will also rotate in the direction of movement. Then, the piston rod 10 telescopically pulls the push rod 12 back from the upper side of the limiting slide 7, thus avoiding contact with the outer plastic parts.

[0021] like Figure 3 As shown, the other end of the push rod 12 slides in a limiting groove 7. The length of the push rod 12 is less than the width of the material feeding slide 1. When the push rod 12 moves in the limiting groove 7, the length of the push rod 12 is prevented from touching the photoelectric sensor 6. Therefore, the length of the push rod 12 is less than the width of the material feeding slide 1, so that the push rod 12 will not touch the photoelectric sensor 6 during its movement.

[0022] like Figure 1 , Figure 4 and Figure 5As shown, the upper end of the damping shock absorber 14 is hinged to both sides of the lower front end of the unloading slide 1. A servo motor 15 is fixedly installed on the outer side of the support frame 13. The output end of the servo motor 15 is fixedly connected to a contact block 16. The contact block 16 rotates and contacts the lower front end of the unloading slide 1, causing the unloading slide 1 to vibrate. The damping shock absorber 14 at the lower front end of the unloading slide 1 plays a role in damping the vibration. The vibration allows the plastic outer shell inside the front end of the unloading slide 1 to be unloaded smoothly, avoiding the situation of sticking to the guide post inside the unloading slide 1 and causing blockage.

[0023] like Figure 4 and Figure 5 As shown, the contact block 16 is oval-shaped. The upper end of the contact block 16 abuts against the lower part of the feeding slide 1. By turning on the servo motor 15, the contact block 16 is driven to rotate. Since the contact block 16 is oval-shaped, the upper end of the contact block 16 abuts against the lower part of the feeding slide 1, causing the feeding slide 1 to vibrate, which has the effect of preventing blockage.

[0024] The working principle of this utility model is as follows: First, place the entire unloading slide 1 on one side of the injection mold. Then, according to the height of the injection mold, adjust the telescopic rod 2 and the unloading slide 1 by extending and retracting them from the support column 3. After adjusting the height, fix them by bolts 5 through the support column 3 and the telescopic rod 2. Then, connect the external power supply. When the outer shell injection part is ejected into the unloading slide 1 after being formed in the injection molding machine, the electric push rod 9 inside the unloading slide 1 is higher than the outer shell injection part, so there is no need to worry about it blocking the normal unloading of the outer shell injection part. Then, the photoelectric sensor 6 inside the unloading slide 1 can detect abnormalities in the outer shell plastic part inside the unloading slide 1. When the outer shell plastic part is stationary for more than 3 seconds, the input end of the photoelectric sensor 6 is fixedly connected to the output end of the electric push rod 9, and the switch of the electric push rod 9 is turned on. This pushes the internal piston rod 10 and the front push rod 12 to move under the limiting slide groove 7 inside the unloading slide 1, thereby pushing the blocked outer shell plastic part. At the same time, after pushing to the bottom, the limiting slide... The groove 7 is arc-shaped, allowing the push rod 12 to move from the lower side of the limiting groove 7 to the upper side of the limiting groove 7. Since the electric push rod 9 is also rotatably connected to the inner wall of the unloading slide 1, as the push rod 12 moves inside the limiting groove 7, the electric push rod 9 will also rotate in the direction of movement. Then, the piston rod 10 will extend and retract to pull the push rod 12 back from the upper side of the limiting groove 7, thus preventing the push rod 12 from contacting other outer plastic parts when it returns. After that, the outer plastic parts at the front end of the unloading slide 1 slide down and enter the rear end. If the rear end encounters a blockage, simply turn on the servo motors 15 on both sides below the unloading slide 1 to drive the abutment block 16 to rotate. The abutment block 16 is oval, so that the upper end of the abutment block 16 abuts against the lower part of the unloading slide 1, causing the unloading slide 1 to vibrate, thus preventing the outer plastic parts from sticking to the inside of the unloading slide 1 and causing blockage again. In this way, the use process of the unloading mechanism for the outer injection molded part with anti-blocking mechanism is completed.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
